COMPACT POWDER HOLDER.

Application filed January 11, 1926. Serial No. 80,514.

My present invention relates to toiletl requisites and more particularlyto containers or holders for face powder. Such powder is now largelysold in compressed cakes contained in suitable boXes and supportedtherein in a metallic holder that prevents it from cracking or chippingand at the same time constitutes a re-fill for the boX or vanity casewhen desired. Such a holder is shown in my pending application SerialNumber (S34-,662, filed April 26, 1923 and the present invention is animprovement on the construction therein shown whereby the holder is madelight, strong and unyieldmg but is additionally provided with means forlocking the powder cake therein. To these and other ends the inventionresides in certain improvements and combinations. of parts all as willbe hereinafter more fully described, the novel features being pointedout in the claim at the end of the specifi cation.

In the drawings:

Figure l is a central section through 'a powder box containing a cakeand holder constructed in accordance with and illustrating oneembodiment of my invention.

Figure 2 is an enlarged vertical section through the powder holder andcake;

Figure 3 is a bottom view of the powder holder, and n Figure 4L is a topview thereof before it is filled.

Similar reference numerals throughout the several views indicate thesame parts.

Referring first to Figure l, l indicates the bodyv and 2, the lid of acommon form of powder box having a cylindrical lining wall 3 over whichthe flanges of the lid engage. Within the box is a dome shaped powdercake i within a metallic holder indicated generally at 5.

The holder consists of a shallow dish or tray embodying a bottom 6 andal flanged rim 7 and as before stated, this must be light in weight sothat it is stamped from thin sheet metal. The powder is compacted intothe holder under pressure by suitable filling machinery in an eli'ort tocause it to cling so intimately to the surfaces of the holder that itwill adhere thereto. However, a difficulty has been experienced in thatthe pressure exerted on the holder in filling tends to cause the sidewalls or liange 7 to spring or give outwardly under the lateral pressureof the powder. This, in turn, causes the bottom 6 to bulge upwardly sothat while the cake 4 is in actual process of being molded it is moldedto a tray or holder that is in distorted condition. Thus when thepressure is relieved the slightly convex bottom 6 to which the cake hasbeen shaped recedes to a normal flat condition and drawsaway from anintimate supporting contact with the powder making loosening andbreakage probable if not inevitable.

My prior application above identified, discloses means for correctingthese diiculties in a very simple manner. An annular groove 8 is punchedin the bottom 6 of the holder closely adjacent to the fiange or sidewall 7 which forms a corresponding annuA lar rib on the inside of theholder. The crimping of the metal has the well known effect of hardeningthe metal so that it is less flexible and gives less of a tendency forthe wall 7 to spread. It also strengthens the bottom of the holder inthe region where the relative movement of the flange and bottom occurs.

In the practice of the present invention l -employ this invention of myprior application but also provide additional means for adding rigidityto the holder and at the same time locking the powder cake 4 in place.This consists of an inwardly turned flange 8 on the side wall 7 thatprojects downwardly at an angle as clearly shown in Figure 2. When thepowder cake 4; is pressed into place, it flows under this flange andinto locking engagement therewith. Aside from this locking function, theformation of this flange gives a smooth and rounded edge to the holderthat is pleasing to the touch and also gives additional surface for theengagement of locking devices that may be used to retain the holder in aspecial receptacle.
